HI

I have a problem with a 2D filled Contour plots.

Just placing a chart with a 2D contour series and using the code below:

Series1->IrregularGrid = true;
Series1->Brush->Style = bsSolid;
for (int i=0;i<10;i++)
{
for (int j=0;j<25;j++)
Series1->AddXYZ(i,i*j-random(0.5*i*j),j);
}

This gives contours which are not filled correctly (e.g. filled area outside contour lines and areas with white triangles). If I just use AddXYZ (i,i*j,j); the contour is drawn perfectly.

Any help will be appriciated, Jørgen

Hi Jørgen,

This seems a defect to me and added it (TV52013073) to the bug list to be fixed for future releases.

Thanks!


Is there any works arounds so that I can display irregular filled 2D contours? I.e. by using other series types?

Jørgen

Hi Jørgen,

I'm afraid not. You could try using ColorGrid series but you'd hardly obtain a similar chart.

Hi!
Is this problem fixed already?

My colleagues are preparing the dev environment for the project to be launched quite soon,
in which the contour drawing and color-filling features are required.
Can I recommend them to useTeeChart for this purpose? Or not yet?

Hi HotSteemar,

The issue is not fixed yet. However we are working on it at the present moment. The more irregular the contour series is the worst filling is. You could try how it works depending on the kind of data you need to plot.

Hi Narcis

Has this issue been fixed in 8.06?

Regards Jørgen

Hi Jørgen,

No, we haven't been able to include that in v8.06 but will continue working on a solution to this problem.
